For record type, use selectedLabels: local!selected.name.
For better understandign can you please share full code.

I understand your code.I try to map with record type to save the new value or saved one value.
then in picker field the first alphabet is only visible.
For example, add "xyz" and once select then "x" is visible.
Not sure why this is happening.

Have you tried the above code as-is to understand how it works?
Are you getting an issue with my exact code?

Just adding another version on top of Shubham Version, so that it gives clear understanding to the user that new value is being added. You can modify the values in the saveInto of the pickerfield based on your requirement.

PickerField:

a!localVariables(
  local!matches: where(
    a!forEach(
      items: ri!labels, 
      expression: search( ri!filter, fv!item)
    )
  ),
  a!dataSubset(
    data:  if(
      and(
        contains(
          trim(lower(ri!identifiers)),
          trim(lower(ri!filter))
        )
      ),
      index( ri!identifiers, local!matches),
      append(
        touniformstring(
          index(
            { ri!identifiers },
            local!matches,
            {}
          )
        ),
        ri!filter & " (Add new)"
      )
    ),
    identifiers: if(
      and(
        contains(
          trim(lower(ri!identifiers)),
          trim(lower(ri!filter))
        )
      ),
      index( ri!identifiers, local!matches),
      append(
        touniformstring(
          index(
            { ri!identifiers },
            local!matches,
            {}
          )
        ),
        ri!filter
      )
    )
  )
)

I tried to mimic this scenario

Interface -

a!localVariables(
  local!countries: { "USA", "India", "Canada" },
  local!selected: null,
  a!pickerFieldCustom(
    label: "Country",
    suggestFunction: rule!POC_CountrySuggest(
      filter: _,
      labels: local!countries,
      identifiers: local!countries
    ),
    value: local!selected,
    saveInto: local!selected,
    selectedLabels: local!selected
  )
)

Suggestion Function -

a!localVariables(
  local!matches: where(search(ri!filter, ri!labels)),
  if(
    length(local!matches) > 0,
    a!dataSubset(
      data: index(ri!labels, local!matches),
      identifiers: index(ri!identifiers, local!matches)
    ),
    a!dataSubset(
      data: ri!filter,
      identifiers: ri!filter
    )
  )
)
